Received docs. One question, there are 78xx, 79xx, 78lxx and 79lxx ICs called for. I am guessing a linear regulator either 7815 or 7824 and 7915 or 7924 depending on desired output. Brand not critical.
Tnx

As in any of our heapdone amp projects, you can use any regulators for the main amp which are 78xx / 79xx pin-compatible (TO220).
Almost all of our projects are supplied with discrete regulators of different sorts.
Voltage to suit that particular amp.

The 78Lxx / 79Lxx are for the SHPP.
We recommend same voltage as the main amp.

Fuse depends on power consumption.
Suppose you use a +/-24V UTHAiM with 22Vrms Talema.
And let's say you want to bias at 180mA.
And mains is 115Vac
Total power = 2 x 2 x 22 x 1.414 x0.18 = 23W.
Mains current = 0.2A.
